Sermon for
Trinity 7, July 19, 2026
To all those loved by God…called to be
saints: Grace to you and peace from God our Father and the Lord Jesus Christ.
Amen.
Ephesians 6:10-18 10Finally,
be strong in the Lord and in his mighty power.
11Put on the full armor of God, so that you can stand against
the schemes of the Devil. 12For
our struggle is not against flesh and blood, but against the rulers, against
the authorities, against the world rulers of this darkness, against the
spiritual forces of evil in the heavenly places. 13For this reason, take up the
full armor of God, so that you will be able to take a stand on the evil day
and, after you have done everything, to stand.
14Stand, then, with the belt of truth buckled around your
waist, with the breastplate of righteousness fastened in place, 15and
with the readiness that comes from the gospel of peace tied to your feet like
sandals. 16At all times hold
up the shield of faith, with which you will be able to extinguish all the
flaming arrows of the Evil One. 17Also
take the helmet of salvation and the sword of the Spirit, which is the word of
God. 18At every opportunity,
pray in the Spirit with every kind of prayer and petition. Stay alert for the same reason, always
persevering in your intercession for all the saints. (EHV)
Baptism=Putting
on the full armor of God.
Dear fellow redeemed,
Imagine
yourself going into battle against the forces of a modern superpower such as
the United States, China, or Russia, with all its soldiers, tanks, heat-seeking
missiles, armor penetrating bullets, and even atomic weapons at its disposal,
but the only weapon in your hand is a tennis racket. Just one basically unarmed person against
thousands of soldiers equipped with all the powerful, laser-focused modern
weapons. It doesn’t seem like a fair
fight at all, does it?
A teenage boy once entered
such a battle. King Saul finally
relented and allowed young David to go up, nearly unarmed, against the most
fearsome military weapon of their time.
To the Israelites looking on, it seemed like a total mismatch. Most of them likely didn’t even see that
David carried a sling. However, David
wasn’t unarmed, but rather, Goliath was the one without any protection. You see, David was armed with faith in the
Almighty God, and he possessed the helmet of salvation, the shield of faith,
and the sword of the Spirit. It was a
complete mismatch, but in David’s favor, and Goliath fell dead at his feet.
You and I don’t have to
fight nine or ten-foot-tall giants, but we do face many extremely powerful enemies
determined to destroy us, along with our children and all the rest of the people
we love. We face forces of evil that are
intent on separating us from the love of God and keeping us enslaved under the
control of the devil and his allies.
Indeed, “Our struggle is not against flesh and blood, but against the
rulers, against the authorities, against the world rulers of this darkness,
against the spiritual forces of evil in the heavenly places.” The prince of this world, the devil, seems to
have all the advantage. However, we are
not left defenseless because God blesses us in the spiritual realms with Baptism=Putting
on the full armor of God.
When Paul wrote this
letter, the picture of a Roman soldier fully equipped for battle was a common
site, and every person would have immediately recognized the picture. However, in those ancient times, everyone
understood that in a battle, women and children would be totally defenseless if
the soldiers protecting them should fall.
You and I, on the other hand, are given defenses that work for anyone
who believes. Baptism equips every
person on whom God puts His name with equal status in the battle. We don’t have to rely on our strength or
ability to reason or fight. Just like
David against Goliath, it is the Almighty God of Israel who has conquered our
foes.
Paul wrote, “Finally,
be strong in the Lord and in his mighty power.
Put on the full armor of God, so that you can stand against the schemes
of the Devil.” Apart from the
promises of God’s Word, we have no way to resist the devil with his lies and
accusations. Without faith in Christ
Jesus, what defense could we raise when the devil calls us liars, thieves, and
murderers? All of us, in one way or
another, have violated every commandment Almighty God has given. We all have lusted after things or people
that are not ours. We all have
questioned the earthly authorities put in power over us: our parents,
grandparents, police, and political rulers.
I dare say we all have even questioned God.
If we should be left to stand
on our own, who among men could withstand those flaming arrows aimed directly
into our hearts? Without a defender, we
would have much less chance than the soldiers of Custer’s last stand. Every accusation against us would send us
straight to hell. Every baby born into
this world would be destined to the fires of eternal torment.
But oh, what great joy is
ours! Our Savior has not left us
defenseless. When Jesus instituted
baptism, He was giving us a gift of immeasurable worth, for in baptism our Lord
dresses us in His perfect holiness and obedience to God’s will. In baptism, the Holy Spirit shields our
hearts from all accusations because Jesus paid the full and lasting penalty of
death for all our sins, and in the water and Word of baptism, He washes us
clean. In baptism, God the Father puts
His name, His seal of ownership, on the head of every child (whatever the age)
upon which the water and Word of God’s grace is poured. In baptism, God dresses us from head to toe
in everything we need so that the devil can have no power over us. In fact, in baptism, God credits us with the
righteousness Jesus lived. Thus,
Baptism=Putting on the full armor of God.
Now, if you can imagine a
Roman soldier dressing his young child in the armor of a soldier, we could all
understand that as that child grew, he would need to keep rearming and updating
his equipment for the day at hand. Likewise,
we too value the training that education in God’s Word gives. The faithful Christian parent doesn’t stop
with baptism alone, but shares the truths of Scripture so that the children also
know the gift of God’s love and the sacrifice Jesus made to make His little ones
holy in God’s eyes. We keep that
training and instruction going, not just until confirmation, but on throughout
the child’s life, and even when they reach adulthood and our control seemingly
disappears into the ether, we keep pleading and praying that God would continue
to watch over the children and defend them from Satan’s deceptions and lies.
Likewise, every soldier
going out to battle was continually diligent in keeping his equipment in top
condition so that he would always be perfectly prepared to confront the enemy
for his king. Now, connect that with our
spiritual life. We too need to keep our armor
in tip-top shape. Not that we can do
anything to improve God’s Word or promise, but we need to continue in His Word
on a daily and weekly basis to remail fully prepared for the battles we face while
we study “the Holy Scriptures, which are able to make you wise for salvation
through faith in Christ Jesus.” (2 Timothy 3:15)
In that daily preparation,
we return again and again to our baptisms.
That is what repentance is, a turning away from the distractions and
evils of this world to trusting again in all God has given us. At every worship service, we stand before the
Lord and plead for His forgiveness and mercy.
We confess our sins in humble remorse for our failures. Yet, that is hardly the end of the
story. For in every true repentance
there is faith in God’s forgiveness, for His Son Jesus lived and died on our
behalf. And then we rejoice, knowing and
hearing again and again of Jesus’ resurrection from the grave which signifies
that His sacrifice really, truly did the job God had assigned to it which was
to wipe away our guilt and bring us into the freedom of forgiveness and eternal
peace with our Creator and God.
Then, properly dressed for
battle, “With the belt of truth buckled around your waist, with the
breastplate of righteousness fastened in place, and with the readiness that
comes from the gospel of peace tied to your feet like sandals,” we can go
boldly forth to face the world, confident in the forgiveness Christ has won for
us, and rejoicing for the life the Holy Spirit has poured into us, ready to
tell the demons they can have no power over us, and to share with friend and
neighbor and sometimes enemies, the truth of all God has done for us and for
them.
Dear friends, so many
people confuse church and religion as being some tedious duty that defies
understanding or any reason to be involved.
Those troubled souls are stuck in the devil’s lies. The only thing that can rescue them from that
darkness is the Light of Jesus Christ.
We can preach law at them, and sometimes we must do so, but whenever a
person is troubled by the trials and torments of this cruel world and the guilt
that so surrounds us daily, the time is right to proclaim the Gospel of Jesus
Christ in all its power and glory. We
don’t have to stand on soapboxes and obnoxiously condemn our neighbors. We need rather, to bring to them the milk of
God’s Word so that even more of those whom God loved through the sacrifice of
His Son may hear the testimony that brings life.
Sometimes, it may seem
like there is nothing we can do to control the evil in this world, and nothing
we can do when we are rejected and perhaps even cursed and despised for walking
with Jesus. It is at all those times,
and really every other circumstance, as well, that we again give heed to Paul’s
instruction, “At every opportunity, pray in the Spirit with every kind of
prayer and petition. Stay alert for the
same reason, always persevering in your intercession for all the saints.” We pray for friends and neighbors. We pray for each other. We give thanks to God for the forgiveness and
life He brings, and pray for His protection, strength, and guidance. We pray that God would give us opportunities
to share His Word and baptism with many other hurting souls. And again, we thank God that Baptism=Putting
on the full armor of God. Amen.
God
will fully supply your every need, according to his glorious riches in Christ
Jesus. Now to our God and Father be
glory forever and ever! Amen.
